A remote monitoring system includes an elevator including a control microcomputer for controlling the operation, and a monitoring terminal communicably connected to the control microcomputer of the elevator and for remotely monitoring the operation of the elevator (Patent Document 1). reference).

On the other hand, the control microcomputer stores specification data, and the specification of the elevator can be changed by changing the specification data. For example, by changing the specification data of the control microcomputer, it is possible to change the rated speed, control the on/off of the air conditioning fan in the car, and adjust the elevator specifications such as adjusting the volume of the speaker installed in the car. ..

By the way, if the specification data of the control microcomputer is changed, an unexpected abnormality may occur in the operation of the elevator. Therefore, the specification data of the control microcomputer should be changed by a technician dispatched to the site (elevator whose specification data is to be changed). Therefore, it was performed after confirming that there were no users in the elevator (for example, after confirming that the car was unmanned (empty car state)). As described above, when the specification data of the control microcomputer was changed, it took a lot of time and labor to dispatch the technician to the site so that the change would not affect the user.

Hereinafter, a remote monitoring system for a lifting device according to the present invention (hereinafter, simply referred to as a remote monitoring system) will be described. The remote monitoring system is, for example, a system that remotely monitors the operating status of the elevator. In this remote monitoring system, the elevator outputs, for example, an abnormality signal when an abnormality such as an operation stop occurs, and a monitoring terminal connected to the elevator notifies the elevator abnormality based on the abnormality signal. By performing such a notification, the technician who is monitoring the monitoring terminal can send the technician to the site (elevator having an abnormality). The technician who arrives at the site may deal with the abnormality of the elevator by changing, for example, the specifications of the elevator (specifications regarding the drive system, control specifications regarding the operation, etc.). Specifically, a technician may deal with an abnormality in the elevator by changing the specifications of the elevator by rewriting the data regarding the specifications of the elevator.

On the other hand, there is also a request to change the specifications of the elevator from a place away from the elevator. In response to this request, in this remote monitoring system, if it is possible to judge that the car is unattended based on the information obtained from the elevator, by rewriting the data related to the specifications in the elevator, the data related to the specifications will be temporarily rewritten, causing a malfunction in the elevator. Even if occurs, the specifications of the elevator can be changed while suppressing the influence on the user. Although the elevator includes an elevator and an escalator, a remote monitoring system for the elevator will be described below.

As shown in FIG. 1, the remote monitoring system includes an elevator 2 having a control microcomputer 20 and a car 21, and at least a server (processing unit) 3 connected to the control microcomputer 20. The remote monitoring system 1 of the present embodiment includes a technician terminal (terminal) 4 connectable to the server 3. Further, the remote monitoring system 1 of this embodiment includes a remote monitoring unit 5 and a monitoring terminal 6 provided between the control microcomputer 20 and the server 3.

Although one monitoring terminal 6 is shown in FIG. 1, the remote monitoring system 1 of the present embodiment is provided with a plurality of monitoring terminals 6. Further, since the elevator 2 is connected to each of the monitoring terminals 6 via the communication system R1, the remote monitoring system 1 of the present embodiment includes a plurality of elevators. The communication system R1 can communicate with the monitoring terminal 6 via the remote monitoring unit 5 and the telephone line in order from the control microcomputer 20, and from the monitoring terminal 6 conversely via the telephone line and the remote monitoring unit 5. Is a communication system capable of communicating with the elevator 2. Further, although one engineer terminal 4 is shown in FIG. 1, the remote monitoring system 1 of the present embodiment is provided with a plurality of engineer terminals.

The car 21 of the elevator 2 is connected to the control microcomputer 20 and moves up and down in the hoistway. In the remote monitoring system 1 according to the present embodiment, a button for opening and closing a car or opening and closing a door of a car and an operation status of the elevator 2 are detected in the car 21, and the operation result of the elevator 2 is detected. Various sensors capable of outputting as a signal related to the above are provided. The sensor can output various signals corresponding to the operating status of the elevator 2.

The control microcomputer 20 of the elevator 2 always accepts the output of the information regarding the operation status of the elevator 2 by the sensor (the sensor provided in the car 21). Further, when information is output from the sensor, the control microcomputer 20 may, for example, operate a button in the car, position information of the car, car door opening/closing information, or a motor for raising or lowering the car based on the output information. It is possible to output the drive information of, and an event code indicating a power failure or the like. The event code includes an event code indicating a failure (event code indicating an abnormality of the elevator 2 such as a failure of a car door or a landing door, an overrun of a car, a life of a car lighting, etc.).

In the remote monitoring system 1 of the present embodiment, the control microcomputer 20 includes a first storage unit (storage unit) 200 that rewritably stores data regarding the specifications of the elevator 2. In the remote monitoring system 1 of this embodiment, the first storage unit 200 can be rewritten by the server 3. The specifications of the elevator 2 include specifications for a drive system and control specifications for driving. Specifically, the specifications of the elevator 2 include rated speed, on/off control of a fan for air conditioning in the car, adjustment of the volume of a speaker provided in the car, and the like. Further, the data regarding the specifications includes a program regarding the specifications, numerical values used in this program, and the like.

The remote monitoring unit 5 always accepts the output of a signal from the control microcomputer 20 (for example, an event code related to button operation in the car or an event code indicating a failure), and when the control microcomputer 20 outputs the signal. This signal and information on the elevator that output the signal (for example, the elevator identification number (machine number) of the elevator 2) are output to the monitoring terminal 6. In the remote monitoring system 1 according to the present embodiment, when the server 3 outputs an input request signal described later, the remote monitoring unit 5 controls the event code indicating the opening/closing information of the car door from the control microcomputer 20 and the button operation in the car. When the event code indicating is output, the fact is output to the server 3.

The monitoring terminal 6 of the present embodiment, for example, monitors a large number of elevators installed in a plurality of areas and is installed in a monitoring center or the like which is a building away from the target elevator. An observer (operator) is resident at the monitoring center of this embodiment. The monitoring terminal 6 can be connected to the server 3 and also to the technician terminal 4 via the Internet.

Information (for example, the machine number of the elevator 2) and a signal regarding the elevator that is the output source are output from the control microcomputer 20 to the monitoring terminal 6 via the communication system R1. The monitoring terminal 6 has, for example, a second display unit 60 capable of displaying information on the elevator 2 as an output source (for example, an elevator identification number) and the content of a signal from the control microcomputer 20 (for example, an event code). The second display unit 60 is, for example, a display. The monitoring terminal 6 also has a second input unit 61 that can be operated by a monitoring staff. The second input unit 61 is, for example, a keyboard.

When the control microcomputer 20 outputs the information on the elevator 2 as the output source (for example, the elevator identification number) and the abnormality signal, the monitoring terminal 6 causes the second display unit 60 to display the information on the elevator 2 as the output source (for example, the elevator identification number). By displaying the number) and the content of the abnormality signal (for example, an event code indicating the abnormality), the abnormality related to the elevator 2 is notified to the surveillance staff. By checking this display, the observer can grasp the abnormality of the elevator 2, operate the second input unit 61 as necessary, request the technician to be dispatched, or remotely (when an abnormality occurs, You can request a response at a place away from the existing elevator 2. In the remote monitoring system 1 of the present embodiment, when the monitoring terminal 6 makes such a request to the technician, in addition to the notification to the technician terminal 4, information on the elevator 2 that is the output source (for example, The elevator identification number) and the content of the abnormality signal (for example, an event code indicating abnormality) are also output.

The technician terminal 4 is, for example, a terminal such as a PDA (Personal Digital Assistant), a smartphone, or a laptop computer, and can communicate with the server 3 via the Internet. Further, the engineer terminal 4 is carried by an engineer who can deal with the abnormality of the elevator 2.

In the remote monitoring system 1 according to the present embodiment, the technician terminal 4 outputs the information output from the monitoring terminal 6 (for example, the information regarding the seconded request from the monitoring terminal 6 and the request for remote response) and the information output from the server 3 ( For example, the content of a signal output from the control microcomputer 20 (for example, an event code) and information on the elevator (elevating device) 2 that is the output source (for example, an elevator identification number) during the operation after changing the specification data described later. , And a first display unit 40 capable of displaying a notification or the like from the server 3, and a first input unit 41 capable of inputting specification information by a technician The first display unit 40 is, for example, a display. The first input unit 41 is, for example, an input key, a keyboard, etc. When the engineer terminal 4 includes a touch panel display, this display also serves as the first display unit 40 and the first input unit 41.

The specification information is information related to the specifications of the elevator 2 (specifications regarding the drive system and control specifications regarding the operation). Specifically, the specification information includes, for example, change of rated speed, change of acceleration when the car is moved up and down, change of stop position of car, change of on/off control of lighting in the car, on/off control of fan for air conditioning in the car. This is information about changes, changes in the volume of speakers installed in the car, and so on.

For example, when the technician terminal 4 is notified of a remote response request from the monitoring terminal 6, this fact, information of the elevator 2 that is the output source (for example, the elevator identification number), and the content of the abnormal signal (for example, abnormal) Is displayed on the first display section 40. When the technician who confirms these displays inputs the specification information regarding the changed specifications through the first input unit 41, the engineer terminal 4 outputs the specification information regarding the changed specifications to the server 3.

The server 3 has a second storage unit 30 that stores data relating to the specification information and can temporarily store the specification information relating to the changed specification input from the engineer terminal 4.

The second storage unit 30 stores the specification information whose input is predicted in association with the rewritable data in the first storage unit 200 of the control microcomputer 20. Specifically, the second storage unit 30 stores the specification information “change of rated speed” in association with the address storing the rated speed in the first storage unit 200. Further, the second storage unit 30 stores, for example, the input specification information, the first data in the first storage unit 200 before rewriting, and the second data rewritten in the first storage unit 200 corresponding to the specification information. I remember it temporarily. In the remote monitoring system 1 according to the present embodiment, the second storage unit 30 also stores the procedure of the trial run after data rewriting described later.

When the specification information regarding the changed specifications is input (for example, when input from the engineer terminal 4), the server 3 determines whether the car 21 is unattended based on the information obtained from the elevator 2, When it is determined that the driver is unattended, the first data stored in the first storage unit 200 of the control microcomputer 20 is rewritten to the second data corresponding to the specification information.

Specifically, when the technician operates the server 3 to input specification information regarding the changed specifications from the technician terminal 4, the server 3 stores this specification information in the second storage unit 30 and also to the remote monitoring unit 5. , “When the control microcomputer 20 receives the output of the event code indicating the opening/closing information of the car door and the event code indicating the button operation in the car, a signal requesting the fact to be input to itself (the server 3) (hereinafter, “Input request signal”)” is output. In addition, the server 3 does not receive the event code indicating that the car door is in the door closed state and the button operation in the car for a predetermined time (for example, 3 minutes) after the request signal is output. If it is, the elevator 2 determines that “the car 21 is unmanned (the empty car is in a stopped state)”. Further, when the server 3 determines that the car 21 is unattended (the empty car is in a stopped state), the specification information stored in the second storage unit 30 (related to the changed specifications input from the engineer terminal 4) Based on the specification information), the first data stored in the first storage unit 200 of the control microcomputer 20 is rewritten to the second data corresponding to the specification information. At the time of this rewriting, the server 3 stores the first data before rewriting and the second data after rewriting in the second storage unit 30.

On the other hand, if the car door is opened within a predetermined time (for example, 3 minutes) after outputting the input request signal to the remote monitoring unit 5, the server 3 will be closed again. Then, it waits until a predetermined time (for example, 3 minutes) elapses without receiving the event code output indicating the button operation in the car. At this time, after the car door is closed again, the server 3 does not output the event code indicating the button operation in the car and a predetermined time (for example, 3 minutes) elapses, and then the above-mentioned first Rewrite one data to the second data.

In addition, when the server 3 receives an event code output indicating a button operation in the car within a predetermined time (for example, 3 minutes) after outputting the input request signal to the remote monitoring unit 5, at that time ( From the time when the event code indicating the button operation in the car is received), the car door is in the closed state, and the event code indicating the button operation in the car is not output for a predetermined time ( Wait for 3 minutes). The server 3 rewrites the above-mentioned first data to the second data if a predetermined time elapses in this state.

If a long time (for example, 30 minutes) elapses after the input request signal is output to the remote monitoring unit 5, the server 3 changes the specifications of the engineer terminal 4 because the car is manned. A message indicating that it cannot be performed (for example, a message such as "The user has been in the car, the specification change was canceled. Please input the specification information again after a while") is output.

In the remote monitoring system 1 of the present embodiment, the server 3 executes the trial run of the elevator 2 after rewriting the data of the control microcomputer 20 in addition to rewriting the data of the control microcomputer 20. Further, when the server 3 confirms an abnormality in the test run after rewriting the data of the control microcomputer 20, the server 3 restores the data of the control microcomputer 20 to the original data. Note that this test operation is, for example, a one-floor reciprocating operation toward the middle floor, and the procedure of this test operation is stored in the second storage unit 30 as described above.

For example, the server 3 operates based on the rewritten second data after the rewriting to the second data in the first storage unit 200 and when the car is determined to be unattended based on the information obtained from the elevator 2. Is executed by the control microcomputer 20. When the server 3 confirms an abnormality in this operation, the server 3 rewrites the changed second data stored in the first storage unit 200 with the pre-change first data. If the specification change is not reflected unless the power supply of the elevator 2 is reset, the server 3 resets the power supply immediately before the operation based on the rewritten second data.

Specifically, the server 3 is rewritten after the rewriting to the second data in the first storage unit 200 of the control microcomputer 20 and when it is determined that the car is unattended based on the information obtained from the elevator 2. When the control microcomputer 20 performs an operation based on the second data and the control microcomputer 20 outputs an event code indicating an abnormality to the remote monitoring unit 5 in this operation, the fact is output to the engineer terminal 4. Output the signal requesting After that, when the control microcomputer 20 outputs an event code indicating an abnormality in this operation, the server 3 stores the first data in the first storage unit 200 based on the first data and the second data stored in the second storage unit 30. The second data after the change is rewritten to the first data before the change.

In the remote monitoring system 1 according to the present embodiment, the server 3 further performs the trial operation when the data of the control microcomputer 20 is returned to the original data after confirming the abnormality in the trial operation after rewriting the data of the control microcomputer 20. If the server 3 confirms an abnormality in this further test operation, it notifies the technician terminal 4 to that effect.

For example, the server 3 determines that the car is unattended after rewriting the changed second data stored in the first storage unit 200 with the pre-change first data and based on the information obtained from the elevator 2. At this time, the control microcomputer 20 is caused to execute the operation based on the rewritten first data before the change. The server 3 notifies the engineer terminal 4 when an abnormality is confirmed in this operation (operation based on the rewritten first data before the change).

Specifically, the server 3 keeps the car door closed for a predetermined time (for example, 3 minutes) after rewriting the changed second data stored in the first storage unit 200 to the pre-change first data. Yes, and if the event code indicating the button operation in the car is not received, the elevator 2 judges that the car 21 is unmanned (the empty car is in a stopped state) and operates the control microcomputer 20. To execute. In addition, when the control microcomputer 20 outputs an event code indicating an abnormality in this operation, the server 3 indicates to the technician terminal 4 that "the abnormality has been confirmed in the operation after the specification change, so the elevator is restored before the specification change. However, the abnormality was not improved.”

In the remote monitoring system 1 of the present embodiment, when the server 3 rewrites the data of the control microcomputer 20 for a predetermined specification change such as a rated speed change or an automatic inspection specification, the above-described test run (hereinafter, referred to as “normal test run”). Also referred to as "."), a trial run different from the normal trial run is performed. For example, the server 3 causes the control microcomputer 20 to execute an operation based on the rewritten second data when rewriting the data of the control microcomputer 20 regarding the change of the rated speed, the automatic inspection specification, etc., and the abnormality is caused in this operation. If not confirmed, the control microcomputer 20 is caused to execute a test operation different from the normal one, and an abnormality is confirmed in this operation. Also in this case, if an abnormality is confirmed in this test operation (test operation different from normal), the server 3 will determine the first storage unit 200 based on the first data and the second data stored in the second storage unit 30. The second data after the change in is rewritten to the first data before the change. When the server 3 determines that the car is unattended, the server 3 causes the control microcomputer 20 to execute an operation (normal test operation and test operation different from normal) based on the rewritten first data before the change, and this operation ( When an abnormality is confirmed in the normal trial operation or the non-normal trial operation), the technician terminal 4 is notified.

Specifically, if the specification change is a change in the rated speed, the server 3 performs a reciprocating operation from the highest floor to the lowest floor as a test operation different from the normal test operation. If the specification change is a change in the automatic inspection specification, the server 3 performs the automatic inspection operation as a test operation different from the normal test operation. The automatic inspection operation is a preset operation automatically executed at the time of maintenance and inspection of the elevator 2 (for example, operation assuming that a car is called on each floor).

In the remote monitoring system 1 described above, the technician uses the information (for example, the event code output from the control microcomputer 20) obtained from the elevator 2 from the location where the technician terminal 4 is present (for example, the technician terminal 4 is not transmitted from the elevator 2). It can be accurately determined that the car is unattended, if it is in a remote location). Further, in the remote monitoring system 1, since the data regarding the specifications stored in the first storage unit 200 of the control microcomputer 20 can be rewritten corresponding to the specification information input from the technician terminal 4, for example, remotely ( The specifications of the control microcomputer 20 can be changed (from a place away from the elevator 2). Furthermore, when the server 3 determines that the car is unattended (there is no user in the car), the data related to the specifications stored in the first storage unit 200 of the control microcomputer 20 is associated with the specification information. Since the data can be rewritten, even if an abnormality occurs in the elevator 2 by changing the data related to the specifications, the influence on the user can be suppressed. As described above, according to the remote monitoring system 1, the specifications of the elevator 2 can be changed remotely while suppressing the influence on the user.

In the remote monitoring system 1 of the present embodiment, if an abnormality occurs in the operation of the elevator 2 by rewriting the first data regarding the specifications stored in the first storage unit 200 of the control microcomputer 20 to the second data, the second The operation of the elevator 2 can be restored by returning the data to the first data.

Further, in the remote monitoring system 1 of the present embodiment, even when the first data regarding the specifications stored in the first storage unit 200 of the control microcomputer 20 is rewritten to the second data and then returned to the first data, the elevator If an abnormality occurs in the operation of No. 2, the fact can be confirmed by the technician terminal 4, and this abnormality can be confirmed remotely (from a place away from the elevator 2), for example.

Further, in the remote monitoring system 1 of the present embodiment, the operation after the first data regarding the specifications stored in the first storage unit 200 of the control microcomputer 20 is rewritten to the second data, the operation is performed on the first floor toward the middle floor. Even if an overrun (moving the car to a position beyond the expected car stop position) occurs due to a specification change, a round trip from the top floor to the bottom floor is performed due to the round-trip operation for a minute. Compared with the case where the car is driven, it is possible to suppress push-up in which the car 21 passes through the uppermost floor and collides, and push-down in which the car 21 passes through the lowermost floor and collides.

The remote monitoring system of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the scope of the present invention. For example, the configuration of another embodiment can be added to the configuration of one embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. In addition, some of the configurations of certain embodiments may be deleted.

For example, although the specification information regarding the changed specifications is input to the server 3 from the engineer terminal 4, the specification information is input to another terminal such as the customer terminal (terminal owned by the user) or the monitoring terminal 6. May be done. If these terminals can be connected to the server 3 via a telephone line, the specification information may be input by calling. In this case, the specification information may be input by these terminals, for example, by inputting voice information for automatic voice guidance.

Further, the server 3 determines whether or not the car is unattended when the car button operation is not performed while the car door is closed for a predetermined time, but the camera provided in the car (for example, It may be possible to determine whether or not the car is unattended by analyzing a captured image of the surveillance camera). In addition, for example, when the surveillance camera is provided with a human sensor, the server 3 may determine whether or not the car is unattended based on the output of the human sensor.

Further, the control microcomputer 20 may perform a part of the series of processes described above performed by the server 3 instead of the server 3. For example, the control microcomputer 20 determines whether or not the car is unattended, rewrites the first data from the first data in the first storage unit 200 to the second data based on the specification information, and performs a test operation after the data is rewritten. However, the specification change input from the engineer terminal 4 is output to the control microcomputer 20, and the notification is sent to the engineer terminal 4 (the abnormality is confirmed by the operation based on the second data after the change, and the rewritten before-change It may be possible to notify that the abnormality is confirmed even in the operation based on the first data). Further, instead of the server 3, another terminal such as the monitoring terminal 6 determines whether the car is unattended, rewrites the first data in the first storage unit 200 to the second data based on the specification information, or the like. You may perform a series of processes.

Although the remote monitoring system 1 of the above embodiment includes the plurality of remote monitoring units 5, it may include one remote monitoring unit 5. In this case, the remote monitoring system 1 may include one elevator.

The communication system R1 may include the Internet instead of the telephone line. The communication system R1, for example, as shown in FIG. 2, can communicate with the server 3 via the remote monitoring unit 5 and the Internet in order from the elevator 2, and from the server 3 to the Internet and the remote monitoring unit 5 in reverse. It may be a communication system capable of communicating with the elevator 2 via the. In this case, the communication system between the communication system R1 and the server 3 and the engineer terminal 4 is partly common (Internet).

Although the remote monitoring system 1 of the above-described embodiment is targeted at the elevator as the lifting device, it may be targeted at the escalator. In this case, the remote monitoring system 1 includes a PLC unit (Programmable Logic Controller) as an information output unit instead of the control microcomputer 20, and outputs an event code similarly to the control microcomputer 20. Further, in this case, the specification information is information regarding the specifications of the escalator (for example, change in the ascending/descending speed, the direction of movement (up or down), etc.). Furthermore, in this case, whether or not the step of the escalator is unattended can be determined by, for example, the output of a monitoring camera that images the entire escalator or a human sensor provided in the monitoring camera.
